Gdańsk in July looks nothing like Gdańsk in November, and the difference is bigger than you might expect. This is the guide we'd give a friend with flexible dates — weather, prices, crowd levels and what each month is actually best for.
May and June — the sweet spot
Long days (up to 17 hours of daylight in June), temperatures 15–22°C, restaurants open with their summer terraces but crowds not yet overwhelming. Brzeźno beach is fully walkable, though the sea is still cold (12–17°C). Accommodation prices are noticeably lower than July–August. Our personal favourite for city breaks.
July and August — peak season
Temperatures 20–26°C, the Baltic warms up to 18–22°C — proper swimming weather. Brzeźno, Stogi and Jelitkowo beaches are alive, and evenings on Long Market never quite end. Downsides: the highest prices of the year, crowds at the main attractions, and accommodation that needs to be booked 2–3 months ahead. This is the classic beach season.
September — summer warmth, fewer tourists
Still warm (16–22°C), the sea warmer than in June (18–20°C), and the Old Town noticeably calmer. Often the best month for couples, or for anyone who wants to combine beach and museums. Prices start dropping in the second half of the month.
October and November — museum city break
Shorter days, temperatures 6–14°C, sometimes rainy and windy by the sea. Good months for museums: the WWII Museum, the European Solidarity Centre and the Amber Museum without queues. Restaurants run normal hours, accommodation prices are low, and walks on empty beaches have their own atmosphere.
